341st District Court Judge Beckie Palomo accepted his plea and sentenced Arevalo to serve 10 years in prison.

Arevalo's co-defendant, Alexandra Villalobos, pleaded guilty July 18 to an assault charge and received a 10-year probated sentence. She was ordered to attend anger management classes and pay $17,594 in restitution.

The incident occurred the afternoon of Sept. 7, 2014, when police responded to an assault report in the parking lot of Walmart, 4401 U.S. 83 South.

A caller told police that a man and a pregnant woman had been assaulted.

"When one of the officers arrived at the scene, they met with two victims who stated that a black in color Grand Marquis drove recklessly through the parking lot while they were driving on the wrong side," the District Attorney's Office said.

The complainants yelled at them because they were concerned that the driver could hit a pedestrian, according to court documents.

Police said the suspects returned to where the victims parked.

A woman, later identified as Villalobos, exited the vehicle and attacked the pregnant woman.

But a man, identified as Arevalo, punched him in the face several times, causing a cut and his eye to swell. Arevalo then allegedly kicked the man in the face while he was on the floor.

Both suspects got back in their vehicle and drove away. The criminal complaint states that the 56-year-old man believes he was struck with brass knuckles.

Paramedics took him to Laredo Medical Center for treatment. He was later flown to San Antonio for treatment to his eye.

The duo were arrested and charged by police with aggravated assault causing serious bodily injury after investigators received information on their identities and a detailed description of the vehicle involved in the incident.
